Short code options to suit your business
Discover flexible short code options that match your messaging needs. Choose a shared number with keywords, or a dedicated code that belongs only to you.
Shared short codes
Use a shared short code with a unique keyword at the start of each message to route replies to your account. A cost-effective way to run campaigns while customers pay only their standard network rate.
Dedicated short codes
Own a short code exclusively and receive every message sent to it, without the need for keywords. Perfect for high-volume messaging, brand visibility and large-scale campaigns.
FreeText short codes
Our ‘FreeText’ service allows respondents to text in for FREE, for example to a marketing campaign. Using FreeText removes the send cost for respondents and helps to increase response rates.

Why choose a short code?
SMS short codes are easy to remember and unmistakably associated with businesses. When a recipient sees a message from a short code, they know it’s from an approved organisation, which can help to establish trust and credibility.
They can be used across multiple campaigns with different keywords, making it easy to track which marketing channels and promotions are performing best. Short codes are also listed in public directories, giving your campaigns added legitimacy.
Most importantly, they are designed for speed. While standard mobile numbers can only send around one message per second, short codes can deliver up to 100 messages per second.
A campaign to 20,000 recipients that could take over five hours with a long number can be completed in just minutes with a short code. For flash sales, limited-time offers and urgent alerts, that speed can make all the difference.
